Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the full burden of behavioral disclosure. It only says 'short catalog,' revealing nothing about side effects, network access, return values, or failure modes. The schema hints that some inputs are discarded, but the description itself is silent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short and front-loaded, but the brevity is under-specification rather than effective conciseness. A single vague clause does not earn its place as an operational tool definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With seven heterogeneous parameters, no annotations, and no output schema, one short clause is wholly insufficient. An agent cannot infer what inputs are meaningful, what the catalog returns, or what constitutes a successful invocation. The definition is incomplete for even a basic call.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides descriptive text for all seven parameters, so schema coverage is high and the baseline is 3. The description adds no parameter-level meaning and does not explain how the listed fields relate to HTTP status codes, but it does not actively misstate the parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description is essentially a noun phrase that restates the tool name: a 'catalog' of 'status codes'. It gives no verb or action, so an agent cannot tell whether the tool lists, looks up, validates, or generates HTTP status codes. It also does not distinguish itself from sibling tools like fetch-status.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided about when to use this tool versus alternatives. There are no conditions, exclusions, or mentions of sibling tools. An agent has no basis for deciding whether status-catalog is the right choice.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
